Great new crag under development, Try to ask around in Chiang Dao, or at the Chiang Mai Rock Climbing Adventures shop for 'Son'. He works on the crag and knows everything there is to know. Good climbing on red sharp-ish limestone with well lucked after bolts/threads/anchors. I believe a guidebook for all the crags around Chiang Dao is soon to be developed.
Small parking area down a track off the main road. Next to the first hut on the track.
